The aim of the work is to study the effectiveness of the concentration of humic acids
of Reasil Humic Vet feed additive on the increase of the feed bioavailability for poultry and the
probability of its negative impact on the safety and marketable characteristics of the final product.
Studies were conducted on the basis of the Saratov State Agrarian University in two similar
groups of broiler chickens ‘Cobb 500’, 100 heads each. Poultry feeding consisted of the same
complete feed, but the drinking water for the broilers of the experimental group was enriched by
humates in the amount of 0.5 ml L
-1
. Based on the data obtained by daily weighing of the poultry
and considering the feed intake, a positive trend of the influence of the feed additive on the
average daily weight gain and feed conversion per unit of production was noted. The results of
slaughter and anatomical cutting of broiler carcasses revealed that metabolic processes were more
active in the body of an experimental poultry, reflected in the intensive growth of muscle tissue
and fat deposition, which contributed to an increase in the yield of edible parts from carcasses by
9.9%. Studies of composition of broiler blood indicate non-toxicity of the recommended
concentration of humates in the feed additive, its stimulation of non-specific resistance of the
organism, contributing to the functioning of the immune system and the development of internal
organs and, as a consequence, ensuring the safety of the products obtained from them.
